HYDRATING BEA'IING AND RFINING MACHINE.

Application led Novemberi20, k1924. Serial No. 751,052.

To all 'whom t may concern:

Be 1t known that I, EDWARD BENTON FRITZ, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented a new and useful Improvement in` Hydrating Beating and Reiining Machines,of which the following is aspecication. V v

This-invention relates to a class of machines whichare adapted'to grinding, beating, disintegrating and reducing of inaterial: and as a more specific application to the reduction ofrags, pulp, paper stock, and such like paper making material. In the making of paper a main result to beattained is the 'reducing and hydrating of the bers so th'at there shall be a uniformity in the product. In accomplishing this result 'my objects are several as will be shown by the description and claimsamy primary objects are economy of space, economy of operation, economy of construction, economyof power, economy of time, maximum beating surface and gravity process.

In the paper makmg lndustry, 1n the preparation of the material for' the paper-ma ing machine there are several processes carried on in which the central work is done in what is commonly known to the art as a beater, and the process consists in beating the fibers into a consistency, or attempt ,at uniformity. Ordinarily ka device and process is used to get the material ready for the. beaten and devices are used to do the refining after it leaves the beaten These machines require large expenditure of power, and involve loss of time in the movement from one process to the other. Inapplicants device theprocess is one andcon- Vtinuous, the material is carried through its various stages by gravity, and the power is minimized. Water being a major port-ion of the hydrating process it assists inthe operation of the machine rather than involving power to move it.

This application is an improvement upon my former application S. N. 574,402, and applies the principle of gravity treatment as set fort-h in that application.

The accompanying drawings illustrate one form of my invention:

Fig.. 1 is a sectional elevation of the machine.

Fig. 2 is a cross section of Fig. 1 taken in the direction of the arrows 2 2.'

Fig. 3 is a cross section of Fig. 1, taken in the direction of the arrows at 3 8.

As shown the mechanism consists mainly of a housing 10, preferably circular, having upon its internal` walls a plurality of channels l'l. in which are positioned a pluralityl of discs .12. Centrally operative in said housing 1s provided a revolvable vertical shaftl7, assembled on which are aplurality of discs 15. The discs 12 are preferably ap-4 proximately quarter sections; primarily so arranged-that they may be moved outwardly or inwardly forI refining adjustment; secondarily, for the purpose of providing clearance around the same; and thirdly, for convenient removal land replacement.. These members 12 are thickest at the wall of the .housing and taper inwardly vas shown at 1.3: and I provide an adjusting means let for advancing or retarding the same. These discs l2 are placed in spaced relation to each other., a clearance space being provided at their interior edges. The discs upon the shaft l? are assembled thereon in spaced relation, and that spaced relation is equal vto the spaced relation between the discs 12: these discs 15 are thick -at the shaft and taper therefrom` outwardly to the edge as indicated at 16: each taper surface is made to parallel the reversed taper surface of the discs 12, and they are arranged to intermesh and cooperate; a clearance space 24 is provided between the periphery of the discs r 15 and the inner wall of thehousing 10, and

a clearance 18 is arranged between the inner` periphery of the discs 12 and the shaft l7l I provide 4an opening 25 in the bottom xvall `of the housing 10 for the passage' of the iinished material into a receptacle 21 from which it may be'removcd through an outlet 2?).

I provide a supply reservoir 19 above the elevation of the housing 10 with a valve The material fed to this machine throughy the channel 27 is made to fall upon the upper of the revolving discs lv and by reason of gravity and the tapering form of the discs the material immediately starts on a downward and outward flow, its movement being accelerated by the revolving of the rotors; passing over the periphery its course would be downward and inward by reason ofthe downward incline of the discs 12, the material being manipulated between the cooperating surfaces during its process downward, outward and inward, some of the material passing directly downward between the clearance'space between the uar-y ter sections; the material passing out o the vchamber at after having travelled its course through the repetition ofits process. In the making of paper stock a very large percentage'of water is used and the mass is very fluid, the intended action being to perfectly disintegrate and hydrate the fibrous material. It will be readily seen that with 'l the device as shown any regulation maybe 25 had of the discs 12, and that a progressive rel finement may be obtained, by a change in means may beemployed for and the fixed elements.

the clearance space between the revolving l The surfaces lof the discs are shown diagrammatically plain but they may be corrugated, or of some irregu lar form, as mayl befound most eicient within .the spirit of the invention. The housing 10 may be made in halves or sections as may be found most convenient to accommodate the removal of the discs, or replacement. I do not limit myself to the specific form of regulation of the discs as shown at 14 as it is very apparent that many positioning and regulating these discs. I ,j

It will be readily apparent that with the mechanism as shown practically any degreeof refinement may begobtained, and inthe specific field of the paper industry the material 'being operated upon can be handled by gravity and continuously, Athe only limthesurfaces of the wall discs, and means for feeding material to the upper portion of the chamber, ywherebysaid material is fed by gravity to each lowerarea while being thrown outwardlyl and-inwardly the revolv- *ing discs cooperating lwiththe stationary y discs to hydrate, disintegratefand refine the fibrous materialas it travels through said l elements, clearance spaces between the rotor vdiscs and the wall discs whereby material fed to the upper portion of the chamber is fed by gravity through the chamber downwardly, the rotor and wall disc elements cooperating to disintegrate and refine the mass as it travels through said machine.

3. In a machine of the character described a vertical chamber having an inlet at the top thereof and an outlet at the bottom, the inner walls thereof having associated therewith a plurality of inwardly tapering disc members spaced apart, a vertically positioned rotor centrally located in said chamber consisting of aplurality oftapering disc members spaced apart with surfaces lying lclosely yadjacent to the surfaces of the wall disc elements, whereby material fed to the upper portion of the chamber is fed by gravity through the chamber, the rotor and wall disc elements cooperating to beat and refine the mass as it travelsi through said machine.

. 4. In -a machine of the character described a vertical chamber, a rotor vertically positioned thereinconsisting of a plurality oftapering discs assembled thereon in spaced relation, a plurality of fixed disc members associated with the internal wall thereof, said wall discs and said rotor discs intermeshing,'their surface planes lying closely adjacent each other, clearance spaces at the outer periphery of the'rotor discs and at l the innerperiphery of the wall discs for the free passa-ge of. materialtherearound, said wall discs being in sections whereby material fed to the upper portion of the chamber is fed by gravity through the chamber downwardly, the rotor and the wall disc elements cooperating to beat and refine the mass as it travels through said machine..

5. In a device for the purposes described a heusingjcontaining a `vertical chamber,-

associated with the inner'wall of said chamber a plurality of removable curved lates,

`said plates being lassembled in series w erein a single seriesforms subtantially a continuous circle except clearance spaces to provide for adjustment.
